Abstract

Reivindicacion 1: Un aparato (100) para obtener un parámetro (140) que describe una variacion de una característica de senal de una senal sobre la base de parámetros del dominio de la transformada real (120) que describe la senal en un dominio de la transformada, el aparato que comprende: un determinador de parámetro (130) configurado para determinar uno o más parámetros de modelo de un modelo de variacion de dominio de la transformada (130a; 1 30c) que describen una evolucion de parámetros del dominio de la transformada en dependencia de uno o más parámetros de modelo (140) que representan una característica de senal, tal que un error de modelo, que representa una desviacion entre una evolucion modelada de los parámetros del dominio de la transformada y una evolucion de los parámetros del dominio de la transformada real, es llevado por debajo de un valor umbral predeterminado o minimizado.Claim 1: An apparatus (100) for obtaining a parameter (140) describing a variation of a signal characteristic of a signal based on parameters of the real transform domain (120) describing the signal in a domain of the signal. transformed, the apparatus comprising: a parameter determiner (130) configured to determine one or more model parameters of a transform domain variation model (130a; 1 30c) that describe an evolution of transform domain parameters depending on one or more model parameters (140) representing a signal characteristic, such as a model error, which represents a deviation between a modeled evolution of the transformed domain parameters and an evolution of the domain parameters of the actual transform, it is brought below a predetermined or minimized threshold value.
